TABLE.

SPECIFICATION forming part Of Letters Patent N0. 699,644, dated May 13, 1,902.

Application led May 2, 1901. Serial No. 581422. (N0 model- To [all whom, it may concern@ Be it known that I, WILLIAM S. BAYNE, a citizen of the United States, residing at Chillicothe, in the county of Ross and State of Ohio, have invented a certain new and useful Improvement in Tables, of which the following is a specification.

My invention relates to the impro vement of tables, and has particular relation to the improvement of library or similar tables adapted for the support of` a dictionary or other work of reference; and the objects of my invention are to provide a table of this class of superior construction and arrangement of parts, to provide in conjunction therewith an improved moving support for a dictionary or similar book or article, whereby the same when not in use may be made to disappear beneath the tabletopto provide improved means for raising and lowering said support, and to produce other improvements in details of construction, arrangement of parts, and operation, Which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure lis a side elevation of the upper` portion of myimproved table. Fig. 2 is a sectional view on line ,e .c of Fig. 4, showing thel book-support in its elevated position. Fig. 3 is a sectional View on line x of Fig. 4, showing said book in its lowered or partiallylowered position. Fig. 4 is a sectional View taken on two planes, as indicated byline y @j of Fig. 2; and Fig. 5 is a detail view in perspective of one ofthe book-support end plates. l

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I produce a table consisting of a horizontal top frame 1, from which depend suitable supporting-legs 2. Hinged to one end of the table-top frame 1 is a top extension board or section 3, which, asindicated more clearly in Fig. 1 of the drawings, is adapted to be folded over onto the table-top frame 1, covering one end of the latter. This top section 3 may, as indicated in Fig. 4, be folded outward and rest upon outwardly-extending brackets 4, which are hinged or pivoted to swing from the corresponding end of the table. The remaining portion of the table-frame 1 is adapted to be covered by a lateral extension top section 5, which may be hinged at one edge to one side ofthe frame 1.

That portion of the table-top frame 1 which is adapted to be covered bythe extension-section 3 is provided with an opening 6, which leads into the upperside of a casing 7, which depends from said top frame. .Tournaled in the lower portion of this casing are the ends of horizontal and parallel bars 8, on the inner end portion of each of which is carried a grooved wheel 9, these grooved wheels being connected through the medium of a cord 10, the ends of which are united, respectively, with said wheels, said cord being of such length as to permit of its being partly coiled on one or the other of the wheels when the latter are rotated. One of the bars 8 has, as indicated more clearly in Figs. 2 and 4 of the drawings, its journaled endl portion extending through the casing 7, and this extension is made to carry an operating handle or crank l1. To each ofthe bars S is secured the outer or rim portions of lifting-rings 12, the rings of said bars being so arranged thereon as to cause one pair of said rings to move within the other when said bars are rotated. Above the lifting-rings 12 is arranged a traveling horizontal book-support comprising a platform or table-section 13 and end extensionplates 14, these end extension-plates hav-- ing 'openings in their outer portions through which pass loosely vertical guide rods 15, which connect the table-top frame with internal casing-brackets 1G. The inner end portions of the plates 14 are provided with downturned ears 14, which serve as bearings for the spindles or ends of parallel rollers 17. It is obvious, however, that these rollers may be journaled in suitable brackets depending from the platform 13.

On that side of the casing on which the operating-handle 11 is employed I provide a suitable catch 18, with which said operatinghandle may be made to engage, as hereinafter described.

The book 19 or other body is supported upon the platform 13.

In order to illustrate the operation of my device, I will assume that the bars 8 are so turned that the lifting-rings 12 are so turned as to lower the lifting-rin gs 's ufficiently to permit the platform 13 to be supported thereon below the table-top, as shown in Fig. 3. Vthen the platform and the body that is supported thereon are in this position, it is obvious that the table-top extension 3 may be folded over the opening, and the lateral extension 5 may likewise be folded upon said table-top to form a level or flush surface oi' the latter. It being desired, however, to raise the book to position foruse the operating-handle 11 is turned, causing a rotation of one of the wheels 9 and a corresponding, although opposite, rotation of the remaining wheel 9 through the cord connection 10. This operation results in so rotating the bars S as to raise the liftingrings 12, which through their frictional contact with the rollers 17 serve to raise the platform 13 until it has lled the opening 6 and is flush with lthe table-top frame. When thus elevated, it is obvious that the book will be in convenient position for use and that the table-top may be brought Hush with its eX- tensions by folding the latter outward to their extended -positions. By engaging the operating-,lever 11 with the catch 18 it will be seen that the book-supporting platform 13 will be locked in its upper or elevated position.

Although but one of the elevating and supporting devices is shown and described herein, itisiobvious that a similar mechanism and construction might be employed beneath th at 'portion of the table which is adapted to be covered by the section 5 and that this separate mechanism might be employed for the movable support of a typewriter or other article.

From the construction and operation herein shown and described it will be seen that simple and comparatively inexpensive mechanism is provided whereby a book,type-Wrter, or other support may be raised to position for use or lowered out of theway when not in use.

It is obvious that my improved table will be exceedingly useful for a studyor library table and that the same may be produced in such ornamental forms as may be desired.

Having now fully described my invention, whatI claim, and desire to secure by Letters Patent, is-

1. In a table, the combination with 'the framework having an opening in the top thereof, of journaled cross-bars 8 below said opening, cam-bodies mounted eccentrically on said cross-bars, a platform above and supported on said cam-bodies and means for rotating said cross-bars, substantially as specified.

2. In a table, the combination with the framework having an opening in its upper side, of journaled crossbars 8 below said opening, cam-bodies carried thereon, a horizontal platform above said cam-bodies, rollers journaled beneath said platform bearing on said cams,rigid guide-rods passing through the end extensions of said platform and means for rotating said cross-bars, substantially as specified.
